Radiation treatment is a common form of cancer therapy that uses high-energy radiation to kill cancer cells and shrink tumors. This treatment can be delivered through external beam radiation, which uses machines to target cancer cells from outside the body, or through internal radiation therapy, where radioactive material is placed directly at the site of the tumor. Radiation treatment is often used in combination with surgery and chemotherapy to effectively treat various types of cancer. It can help prevent cancer recurrence, relieve symptoms, and improve quality of life for cancer patients. Radiation treatment can also be used for non-cancerous conditions such as benign tumors and certain blood disorders.
